The invention relates to a process for the discontinuous burning off of carbon deposited on the heat-resistant exhaust gas filter of an internal combustion engine, particularly a diesel internal combustion engine. At least one metal must be present during this process. The problem of ensuring the combustion of the carbon at the minimum temperature and of achieving a long filter life, is solved in a particularly advantageous manner through the use of an organic complexing agent able to form a complex with the metal and/or an organo-metallic complex compound of the metal with the organic complexing agent. The invention also relates to an apparatus for performing the inventive process. For this purpose, the exhaust gas filter preferably has at least two, at least temporarily separately operable filter units.

A process for intermittently burning off carbon deposits from a heat-resistant exhaust gas filter of an internal combustion engine, said process comprising periodically applying a combustion initiating agent directly to said filter at a temperature sufficient to initiate combustion, said agent being applied in the presence of at least one complex forming metal, and said agent being selected from the group consisting of an organic complexing agent able to form a volatile, organometallic complex compound with said metal and a volatile, organometallic complex compound of said metal with an organic complexing agent.
